Broadleaf weeds differ from grasses how?

• A. They have netted veins that are usually less elongated than that of grass leaves.
• B. They have parallel veins and elongated leaves like grasses.
• C. They have no veins.
• D. They are always taller than grasses.

Answer: (A)

The main idea is how leaf venation differs between the two plant groups. Broadleaf weeds have netted (reticulate) venation, meaning the veins form a branching network, while grasses have parallel veins running the length of the blade. The stated answer captures this by saying broadleaf leaves show netted veins, which are not as elongated as the parallel veins of grass leaves. The other statements would mischaracterize grasses as having no veins, parallel and elongated leaves like grasses is true for grasses but not for broadleaf weeds, or claim height alone distinguishes them, which isn’t reliable.
